Siemens’ Arc Fault Circuit Interrupters (AFCI) Litigation

Kevin Brnich Electric LLC, et al. v. Siemens Industry, Inc. (N.D.

AT&T Data Breach Litigation

Unruh, et al. v. AT&T Mobility LLC (N.D. Ga.): Cohen Milstein is representing a putative class of AT&T customers, whose names, addresses, phone numbers, Social Security numbers, and other personally identifiable information (PII) were the subject of a massive data breach. Plaintiffs claim that upon learning of the breach in August 2021 when hackers auctioned the database of 70 million customers’ PII in an online hacking forum, AT&T denied the breach ever occurred and refused to investigate. Three years later when the contents of the database were publicly leaked on the dark web and independently verified did AT&T admit the breach occurred and began an investigation.
